For most purposes it works like a standard DX2/66. I don't know of 
any software incompatibilities. The actual instructiona are, AFAIR, 
386 rather than 486; this just means that timings are not the same as 
on an Intel 486 DX2/66. I've only used it with one or two network 
cards, but wouldn't anticipate trouble. Not tried Linux but don't 
anticipate trouble.

The only hardware point is that 30-pin SIMMs are used in pairs, not 
in quadruplets. So no, you can't add ONE more. You can add TWO more.
They must be matched by size in pairs; you can have 4+4+1+1.

I was asked about scrapping one of these machines so as to run MS 
Internet Explorer 5. I recommended trying IE5 on the Blue Lightning; 
it worked fine. Not directly relevant to your situation, just 
confirming that it works fine with fairly demading software such as 
Win95, IE5.
